Application 4filed December 21, 1908-- Serial No'. 463,488. l

To all 'whom "it may concern:

Be it known that L'MARTIN S. OrsATA, a

Y citizen of the United States, residing at Grano, in the county of Ward and State of North Dzkota, have invented certain new and useful Improvements in Gang-Flows, of

which the following is a specification;

This invention relates to plows and'has special reference to such4 devices as are known as gang plows.

4.An object of the invention is to Yprovide a device of this character'with means where- -by the (plowecarried by the same may be adjuste vertically and angularly.

The invention has for a further object the provision of a frame of peculiar construction mounted Aupon supporting wheels which is peculiarly adapted to be used as a vehicle when the plows have been detached.

Other objects and Vadvanta es will be aparent fromv the followingl escription and 1t willbe understood that changes in the specific structure shown and described may be made within the scope of the claims with` out departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in which like numerals of' reference indicate similar parts in the several views, Figure 1 is a side elevation of the complete device, Fig. 2 is a transverse section ofa device looking toward the rear of the machine, Fig. 3 is a top plan View of the device, Fier. 4 is a transverse vertical section looking brward of the machine.

Referring to the drawings, l0 and 11 designate the sides of the device which are preferably formed of angleiron and which are` held in parallel relation by means ofthe cross braces 12 and 13 positloned across the opposite extremities thereof.4 The sides 10 and 11 are rovided with depending bearings 14 which are provided with journal boxes l5 at their lower ends for the reception of a shaft 16 which is loosely journaled therethrough 4and is rovided with the supporting'wheels 17 an 18.

The shaft 16A is connected to an engine 36 Vof any suitable constructionwhich 1s mounted upon the brace 13 and beam 33 longitudinally of thesides 10 and 11 and is,

operated by means'of the lever 32t I The beam 33, which is disposed inter-methately across the sides 10 and 11 is provided with a depending shaft 37 upon which is ,disposed -a sleeve 38 adapted for slidable ers 48 longitudinall movement thereon and which is provided with ears 39 for the reception of the lower extremity of the links 40 and for the reception of the extremities of the clevis 41 carextendcd upwardly where it is pivotally enga ed intermediately upon a hand lever 43 whichw is fulcrumed at its lower extremity to 'the beam 334 and extended rearwardly therefrom to -be held in adjusted position by a dog 44 carried by the lever 43 and engaged witlun a segment 45. The cross head-42 is so formed as to receive the forward extremities of the plow beams 46 which are provided with plows 47 of any construction. The plow beams 46 are provided with keep'- mounted thereon in transverse parallel re ation through which is loosely positioned a bail 49 which is journaled in bearings `50 .positioned upon the inner faces ofthe sides 10 and 11 at the rear extremities of the same.

For the purpose of raising the bail 49 and plowbxb'eams 46 a hand lever 51 is fulcrumed upon a raised bracket 52 transversely positioned across the sides 10 and 11,

which is provided with a forwardly ex' .tended arm atvits lower extremity which carries a depended rod 53 which is rotatably disposed intermediately of the crankl shaft 49.

It is thus seen that by the reciprocation of the lever 51 the bail 49is vertically reciprocated. A segment 54 is vertically disposed in juxtaposition to the lever' 51 for the purpose ot locking the lever 5l in adjusted position by the engagement of the dog 55, carried by the lever 51, with the segment 54. The side 10 is provided with a depended brace 56 which pivotally supports a bell crank lever 57, the upper extremity of the longer arm of which is provided with a pedal 58 which is adapted to be operated by the toot of the operator. The opposite arm 50 of the bell-crank lever is slotted as at 59 shown in Fig. 1 and engaged with the bail 49 for the purpose of raising the same upon the forward movement of the pedal 58. The brace 56 is also provided with a lock lever 60 which is concentrically disposed in relation to the bellcrank lever 57 and which is provided with a shoulder 61 for engagement with the bail 49 when the same is in a raised position. The lock lever 60 is provided with a pedal 62 by which the same is adapted to be operated. The roar extremities of the plow .,610 ried upon a cross head 42.. The link 40 is' beams 46 are rovidcd with a cross brace 63 for securing -t e same in parallel. A spring 64 is carried b an arm 65 vertically positioned interme iately ofthe ends of the rear brace l2. The spring 64 is employed for the purpose of assisting the operator to return the plows to their normal upward position on account of the weight of the same. This spring is secured at its lower end to the keeper 48. A journal box (i6 is vertically disposed at the rear extremity. of the beam ll for the reception ot the upper extremity of a shaft 67 which is curved rearwardly at.

.its lower end and provided with an axle box 68 which carries an axle (if) upon which are disposed the'whccls 7() for supporting the rear extremity of the device. A worm gear 71 is carried upon ,the u )per extremity of the shaft 67 and is engage( with a worm 72 carried upon the rear extremity of a shaft 73 mounted in the arms 74 which are up- .wardly extended from the journal box G6.

The forward extremity of the shaft 73 is mounted in a standard 75 positioned upon the side l0 and is provided with a crank arin 76 for engagement by the operator. The raised bracket :'32 is provided with a seat 77 for the operator.

The device is steered through the shaftY 73 which aetuates the vertically disposed shaft (i7 through the worin 72' to throw the wheels 70 .into the desired angle. 'llie angle of the plows with respect. to the ground is regulated b the operation of the lever It?) which vertically reeiprocates thc sleeve 257 to raise lor lower the forward extremities of tbe plow beams 46 while the rear extremities are supported from vertical movement upon the bail Should it be desired to adjust the height of the plows the lever 51 is actuated to raise or lower the bail 4t) and hold the same in'lockcd position by means ot' the dog in engagement with the raelt 54.

If desired the driving engine may be eliminated, and the plow be drawn by means 4 of suitable draft animals.

v What is claimed is l 1. A device of the class described comrising a body portion, means for propeling said body portion carried thereby, a bail mounted in the rear end of said body portion and extended forwardly therefrom, plow beams carried upon said bail at their rear extremities, levers carried by said bod portion for raising und lowering said bai a shaft depended fromthe forward end of saidbody portion, a sleeve slidably disposed on said shaft, a cross head carried by said sleeve for engagement with the forward extreniities of said plow beams, a lever mount'- ed upon said body portion connected to said sleeve for raisin and lowering the saine and a `spring carrie( by said body portion secured at its lower end to said beams for normally holdingtlie same in an upward position.

2. A device of the class described comprising a body portion, a shaft de ended from the forward extremity of sai body portion, a sleeve slidably mounted on said shaft, a hand lever mounted on' said body portion connected to said sleeve for reciprocating the same, a cross head ivotally connected to the lower end of said sleeve, plow beams earricdby said cross head at v'thelower extremity thereof, a bail mounted in the rear end of said body portion, keepers disposed on said plow beams at the rear extremities thereof engaged over said bail, a hand lever carried by said body portion connected to said hail for raising and lowerin the same, a bell crank lever carried by said body portion having one arm thereoffengugcd with said bail, a pedal disposed upon the opposite arml for-en agement with the foot of the operatxir an( a lock lever coneentrically mounted on said body portibrr with Asaid bell-crank lever for engaging said bail.

Tn testimony whereof I affix my signature, in presence ot two witnesses.
